This case report describes a woman presenting with cyclic sciatica resulting from an ovarian cystic endometriosis lesion compressing the sciatic nerve. Magnetic resonance imaging revealed a hemorrhagic mass at the sciatic notch, characterized by specific signal intensities on T1 and T2 weighted sequences that allowed for diagnosis. The authors emphasize that early recognition of this rare manifestation is critical to prevent permanent nerve damage. This paper is centrally about endometriosis — specifically, it details the rare presentation of sciatic nerve compression caused by endometriotic lesions in the pelvic region.

Abstract

STUDY DESIGN: A case of cyclic sciatica secondary to ovarian cyst endometriosis is presented. OBJECTIVES: To report the clinical description and magnetic resonance imaging aspects of cyclic sciatica. SUMMARY OF BACKGROUND DATA: Endometriosis of the sciatic nerve is rare, but must be included in the differential diagnosis of sciatic mononeuropathies. METHODS: The authors report a new case of a woman whose cyclic sciatica was caused by an ovarian cystic endometriosis lesion. RESULTS: Magnetic resonance imaging was described as hyper- and hypointense on T1-weighted sequences, and hyperintense on T2-weighted sequences at the sciatic notch. CONCLUSION: Magnetic resonance imaging may permit a specific diagnosis of this unusual cause of sciatica by showing a hemorrhagic mass in the region of the sciatic nerve. Early recognition is necessary to prevent permanent damage to the sciatic nerve.

Objectives

To report the clinical description and magnetic resonance imaging aspects of cyclic sciatica. Summary of Background Data Endometriosis of the sciatic nerve is rare, but must be included in the differential diagnosis of sciatic mononeuropathies.

Methods

The authors report a new case of a woman whose cyclic sciatica was caused by an ovarian cystic endometriosis lesion.

Results

Magnetic resonance imaging was described as hyper- and hypointense on T1-weighted sequences, and hyperintense on T2-weighted sequences at the sciatic notch.

Conclusion

Magnetic resonance imaging may permit a specific diagnosis of this unusual cause of sciatica by showing a hemorrhagic mass in the region of the sciatic nerve. Early recognition is necessary to prevent permanent damage to the sciatic nerve.
